* affs: get rid of affs_sync_superArtem Bityutskiy2012-07-143-13/+45
| | | | | | | | | | | | | | | | | | This patch makes affs stop using the VFS '->write_super()' method along with the 's_dirt' superblock flag, because they are on their way out. The whole "superblock write-out" VFS infrastructure is served by the 'sync_supers()' kernel thread, which wakes up every 5 (by default) seconds and writes out all dirty superblocks using the '->write_super()' call-back. But the problem with this thread is that it wastes power by waking up the system every 5 seconds, even if there are no diry superblocks, or there are no client file-systems which would need this (e.g., btrfs does not use '->write_super()'). So we want to kill it completely and thus, we need to make file-systems to stop using the '->write_super()' VFS service, and then remove it together with the kernel thread.

* affs: stop setting bm_flagsArtem Bityutskiy2012-07-141-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AFFS stores values '1' and '2' in 'bm_flags', and I fail to see any logic when it prefers one or another. AFFS writes '1' only from '->put_super()', while '->sync_fs()' and '->write_super()' store value '2'. So on the first glance, it looks like we want to have '1' if we unmount. However, this does not really happen in these cases: 1. superblock is written via 'write_super()' then we unmount; 2. we re-mount R/O, then unmount. which are quite typical. I could not find good documentation describing this field, except of one random piece of documentation in the internet which says that -1 means that the root block is valid, which is not consistent with what we have in the Linux AFFS driver. Jan Kara commented on this: "I have some vague recollection that on Amiga boolean was usually encoded as: 0 == false, ~0 == -1 == true. But it has been ages..." Thus, my conclusion is that value of '1' is as good as value of '2' and we can just always use '2'. An Jan Kara suggested to go further: "generally bm_flags handling looks strange. If they are 0, we mount fs read only and thus cannot change them. If they are != 0, we write 2 there. So IMHO if you just removed bm_flags setting, nothing will really happen." So this patch removes the bm_flags setting completely. This makes the "clean" argument of the 'affs_commit_super()' function unneeded, so it is also removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug has been present ever since data-check was introduce in 2.6.16. However it would only fire if a data-check were done on a degraded array, which was only possible if the array has 3 or more devices. This is certainly possible, but is quite uncommon. Since hot-replace was added in 3.3 it can happen more often as the same condition can arise if not all possible replacements are present. The problem is that as soon as we submit the last read request, the 'r1_bio' structure could be freed at any time, so we really should stop looking at it. If the last device is being read from we will stop looking at it. However if the last device is not due to be read from, we will still check the bio pointer in the r1_bio, but the r1_bio might already be free. So use the read_targets counter to make sure we stop looking for bios to submit as soon as we have submitted them all. This fix is suitable for any -stable kernel since 2.6.16.

In both cases there is a race window for an hrtimer interrupt between dropping timekeeper lock, enabling interrupts and clock_was_set() issuing the updates. Any interrupt which arrives in that window will see the new time but operate on stale offsets. So we need to make sure that an hrtimer interrupt always sees a consistent state of time and offsets. ktime_get_update_offsets() allows us to get the current monotonic time and update the per cpu hrtimer base offsets from hrtimer_interrupt() to capture a consistent state of monotonic time and the offsets. The function replaces the existing ktime_get() calls in hrtimer_interrupt(). The overhead of the new function vs. ktime_get() is minimal as it just adds two store operations. This ensures that any changes to realtime or boottime offsets are noticed and stored into the per-cpu hrtimer base structures, prior to any hrtimer expiration and guarantees that timers are not expired early.

Due to that timers based on CLOCK_REALTIME are either expiring a second early or late depending on whether a leap second has been inserted or deleted until an operation is initiated which causes that update. Unless the update happens by some other means this discrepancy between the timekeeping and the hrtimer data stays forever and timers are expired either early or late. The reported immediate workaround - $ data -s "`date`" - is causing a call to clock_was_set() which updates the hrtimer data structures. See: http://www.sheeri.com/content/mysql-and-leap-second-high-cpu-and-fix Add the missing clock_was_set() call to update_wall_time() in case of a leap second event.

This is only the case when vsyscall emulation is in use (vsyscall=emulate is the default). This patch emulates system call entry inside a vsyscall=emulate by populating regs->ax and regs->orig_ax with the system call number prior to calling into seccomp such that all seccomp-dependencies function normally. Additionally, system call return behavior is emulated in line with other vsyscall entrypoints for the trace/trap cases.

Since this driver has been merged at the same time as the core changes it doesn't set this flags and thus its all file operations except IOCTL are not properly serialized. Fix this by adding file ops locking in the driver.
